To all whom t may) concern.'

Be it known that I, SIGMUND L. Gonn-v understood from the following description, l

illustrated by the accompanying drawings, in which: f i

:F ig.- 1 isa longitudinal sectionalview through the `nozzle with the tion for prim-ing;

Fig.V 2 vis a longitudinal sectional View through the nozzle with the parts in proper position to hold the'siphon after-the nozzle has been primed; andv y Fig.a.3 is a longitudinal sectional Viewl through the device with the partsin position for filling or discharge."v

Referring more particularly to the draw.k

ings7 the numeral' indicates lthe body of the Siphon nozzle, whichinay suitablyl be formed as an integral casting. This body member has a longitudinal cylindricalpor!l tion, through 'which a longitudinal bore 6 a. hose 9 and forms a passes and it also 'has two lateral projections 7 and 8, each of which :has a bore communi eating with a central bore 6. One'` of these projections, indicated as 7 ,communicateswith the central bore 6 at a higherv point than the other, indicated as 8, which may suitably be curved upwards andoutwards. The projection or nipple 7 is employed for priming and to the projection 8 is attached conduity leading into the nozzle.

Two plungers 10 and 11 are fitted in the bore 6 and are slidably secured therein by means of set screws 12 and 13 respectively, the ends of which enter longitudinal slots in the plungers. 'The upper plunger 10, the inner end of which is closed, is providedl with a projection 14 preferably of cylin dricaly form, adapted to enter and close a short longitudinal bore or chamber 15 .in the upper end of the lower plunger 11. This short bore or chamber 15 is closed offy by a partition orl plug 16 from a longer longitudinal bore 17 which extends downwardly to substantiallyv the endof the'plunger 11.

parts in posi- 4An angular kerf18 provides'an exit fromy the bore 17, although any other formv of opening may be employed'. 'An opening 194 is drilled` through the "wall of the-plunger 11 above the partition orl plug 16, affording l communication with the bore or chamber 15 and 'an' opening 20 isboredthrough the wall of the plunger llbelow vthe partition affording 'y communication "with or plug '16 the bore 17'."v

VAfter the Iconduit; or `rtube,A 9, from the yesseli to be emptied, "is attachedto{thepro-l Jecting member/- 8, the plungerl is'moved.v l upwardly and" plunger 11'downward'ly, to.

move them infeither direction. In this posi-v tion 'of the vparts the'siphon nozzlemayfbe filled by suctionex'erted on the primer V7 which, in practice, 'would' probably be effectedkby theoperator sucking upon' thetube 7,1'

the Itube 9Ycominunicating with the bore of the l' f projection Sand thisvbore,"fin turn,'coii`imuni7 eating through theopening 19 with the upper short bore, or chamber 15 iiil plungerll, the other endfof which is open'and' comi municates freely with the bore of the primer 7. Whenthe nozzle has Abeeniilled the op-y erator Ypushes plunger 10y down 'and closes the upper end of bore,or chamber 15of .the k plunger 11' therebyvclosing bore lto the" and fniaintaining the siphonxf The primer l y positionl ofthe parts at'this time is indicated in Fig. 2; Ifgi't isnow desiredto fill a bottle or other receptacle thel operator, grasping the device at thebody 5, inserts the end-of the plunger 11 lintouthe neck of the bottle, thel latterl engagingthe shoulder 21 foi'inedbn the plunger 11, and by pressing down on thefbody 5 theflatter Adescends until#` i i itengages theShouIdeiQLthe bore or. 'cham'-l ber '15 remaining rclosed and iilledlwith`A` liquid in 'thisy operation. *,In" thus operating'- the d evicefthe bore 8 moves downwardly to f a position in'which it communicates'with j v the k'opening QO'and the liquidfthereupon siphons freely through the projection 8, the opening 20, the bore 17 and the opening or lerf 18, into the bottle or receptacle to be lled. When it has been. lilled, the .Siphon nozzle is removed from the bottle, or receptacle, and the parts of the device restored to the position shown in Fig. 2 to arrest the flow of liquid from. the device and maintain the Siphon, the bore 8 again communicating through opening 19 With the bore 15. As the bore 15 has been retained full of liquid the Siphon is unbroken. With the parts con structed as stated above to be preferable, the operator, to restore the parts to the position shown in Fig. 2 Would press down- Wardly on the plunger 10 While raising the body 5, in order that the plunger 10 and 11 maintain thepositions relative to each other as shown inthis ligure.

llt Will be noted that any liquid in priming nozzle 7 which has been in contact with the mouth of the operator may be discarded Without affecting the Siphon and thus the device is rendered highly sanitary.` f
